[0002] A vibratory hammer is a device that uses a hydraulic motor to drive an eccentric wheel to rotate at high speed to generate high-frequency vibrations. The vibration energy is transmitted to the pile body through the chuck, causing the soil structure around the pile body to form a fluid state, reducing the friction between the pile body and the soil. The pile body is then sunk into or pulled out of the soil with the force of an excavator to complete the construction work.

[0003] For example, in the patent document with application number 202120454665.5, a fixing structure of a vibration hammer rotating motor and a rotating mechanism with the fixing structure are disclosed, and a structure is specifically disclosed that enables the rotating motor to be firmly supported on the hanger to prevent the rotating motor from falling off due to insufficient support strength.

In this technical solution, when the rotating motor stops working, a large braking force is required to achieve the braking of the device, but there is no good way to relieve the braking force, which makes the device very easy to produce large wear when braking.

[0008] A further technical improvement of the utility model is that the buffer mechanism comprises a rotating clamping rod for squeezing and buffering the buffer brake half gear, and an end limit rod is arranged on the side of the rotating clamping rod.

[0009] A further technical improvement of the utility model is that the rotating clamping rod comprises a first rotating rod and a second rotating rod which are rotatably connected, and the first rotating rod and the second rotating rod are rotatably connected to the connecting shaft through a torsion spring.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-6 As shown, a vibratory hammer rotating hanger with a braking structure includes a driven gear 1, on which a braking mechanism is arranged for realizing a braking operation on the driven gear 1, that is, the braking mechanism includes a buffer brake assembly and an emergency brake assembly, that is, the buffer brake assembly is used to realize the buffering of the braking force, and the braking force is gradually applied to the driven gear 1, thereby gradually realizing the deceleration effect of the rotation of the driven gear 1, avoiding emergency braking of the driven gear 1 under non-essential conditions, and reducing the greater wear of the driven gear 1 during emergency braking; and the emergency brake assembly is based on a direct braking operation when the driven gear 1 needs to be braked urgently. In this process, greater wear will be generated on the mechanical equipment, affecting the service life of the device, but it can have greater safety.

[0025] Specifically, in the present application, the buffer brake assembly includes an adjusting gear 2 and a buffer brake half gear 3, wherein the adjusting gear 2 moves longitudinally under the action of the adjusting telescopic rod 11, and when the adjusting telescopic rod 11 moves the adjusting gear 2 to the corresponding position, the adjusting gear 2 is respectively meshed and connected with the driven gear 1 and the buffer brake half gear 3, and the buffer assembly on the side of the buffer brake half gear 3 is used to achieve the buffering effect, that is, when the driven gear 1 needs to be buffered and braked, the adjusting telescopic rod 11 is started to control the adjusting gear 2 to adjust the height in the longitudinal direction, and the adjusting gear 2 is respectively meshed and connected with the driven gear 1 and the buffer brake half gear 3, so that the buffer assembly on the side of the buffer brake half gear 3 can provide braking force to reduce the wear of the driven gear 1 during emergency braking.

[0026] Its buffer assembly includes an end limit rod 4 and a rotating clamping rod 5, wherein the rotating clamping rod 5 is used to perform rotational buffering on the buffer brake half gear 3. When the rotating clamping rod 5 touches the end limit rod 4, the end limit rod 4 is used to further buffer the force, thereby achieving the provision of braking force and buffering of the driven gear 1 during braking, so that the speed of the driven gear 1 is gradually reduced.

[0027] The rotating clamping rod 5 is respectively located at the first rotating rod 6 and the second rotating rod 9, wherein the first rotating rod 6 and the second rotating rod 9 are respectively rotatably connected to the connecting shaft 10 through a torsion spring. At this time, the buffer brake half gear 3 is located between the first rotating rod 6 and the second rotating rod 9, and the torsion spring is used to limit the rotation of the buffer brake half gear 3, wherein the end limit rod 4 is fixed to the side of the rotating clamping rod 5, wherein the end limit rod 4 includes a first limit rod 7 and a second limit rod 8, wherein the first limit rod 7 and the second limit rod 8 are fixedly connected at a certain angle, wherein the first limit rod 7 is used to limit the first rotating rod 6, and the second limit rod 8 is used to limit the second rotating rod 9.

[0028] In specific use, when it is necessary to limit the rotation of the driven gear 1, the power component of the driven gear 1 stops driving. Under the action of inertia, the driven gear 1 will continue to rotate. The adjustment telescopic rod 11 is started to control the longitudinal movement of the adjustment gear 2 until the adjustment gear 2 is first meshed with the buffer brake half gear 3. Then, the adjustment telescopic rod 11 is continuously started until the buffer brake half gear 3 and the driven gear 1 are meshed. Under the action of the torsion spring and the end limit rod 4, the force on the driven gear 1 is reduced. When the buffer brake half gear 3 rotates to a certain angle, the adjustment telescopic rod is used to 11 moves upward, driving the adjusting gear 2 to move longitudinally and separate from the driven gear 1. At this time, the adjusting gear 2 and the buffer brake half gear 3 maintain meshing, and then under the limiting action of the torsion spring and the end limit rod 4, the buffer brake half gear 3 is reset. At this time, the speed of the driven gear 1 is reduced, and then the longitudinal movement of the adjusting telescopic rod 11 is used to make the adjusting gear 2 mesh with the driven gear 1 again, and the speed of the driven gear 1 is reduced again until the rotation of the driven gear 1 stops. In this process, the speed of the driven gear 1 is buffered and reduced by meshing the adjusting gear 2 with the driven gear 1 multiple times.

[0029] The emergency brake assembly includes an emergency brake half gear 13, wherein the emergency brake half gear 13 is fixedly installed at the output end of the emergency brake telescopic rod, wherein the emergency brake half gear 13 is meshed and connected with the driven gear 1, and the emergency brake half gear 13 and the buffer brake half gear 3 are respectively located on both sides of the driven gear 1. When the emergency brake telescopic rod drives the emergency brake half gear 13 to move longitudinally, the emergency brake half gear 13 is directly meshed and connected with the driven gear 1, and the driven gear 1 is directly braked.

[0030] When the utility model is in use, when it is necessary to limit the rotation of the driven gear 1, the power component of the driven gear 1 stops driving. Under the action of the inertia force, the driven gear 1 will continue to rotate. The adjustment telescopic rod 11 is started to control the adjustment gear 2 to move longitudinally until the adjustment gear 2 is first meshed with the buffer brake half gear 3. Then, the adjustment telescopic rod 11 is continuously started until the buffer brake half gear 3 and the driven gear 1 are meshed. Under the action of the torsion spring and the end limit rod 4, the force of the driven gear 1 is reduced. When the buffer brake half gear 3 rotates to a certain angle, the adjustment telescopic rod 11 is used to control the adjustment gear 2 to move longitudinally. The rod 11 moves upward, driving the adjusting gear 2 to move longitudinally and separate from the driven gear 1. At this time, the adjusting gear 2 and the buffer brake half gear 3 maintain meshing. Subsequently, under the limiting action of the torsion spring and the end limit rod 4, the buffer brake half gear 3 is reset. At this time, the speed of the driven gear 1 is reduced. Subsequently, the longitudinal movement of the adjusting telescopic rod 11 is adjusted to make the adjusting gear 2 mesh with the driven gear 1 again, and the speed of the driven gear 1 is reduced again until the rotation of the driven gear 1 stops. In this process, the speed of the driven gear 1 is buffered and reduced by meshing the adjusting gear 2 with the driven gear 1 multiple times.
